BoonEx licenses can be converted to UNA licenses if you want. You stated you have 2 licenses so, if you want to use one of those licenses (or both if you choose) for UNA, I would suggest sending an email to support@una.io with your BoonEx Dolphin license you want to convert and they can do that for you. 

No need to sell anything or think they do not matter anymore. They are still good :)
